This invention relates to fire extinguisher supports.

*Moreparticularly stated, the invention relates to the grenade type of fireextinguisher'.

* anidtoia holder or supportfor the grenade.

"This invention has "for its salient object toprovide a support for a'grenadefso com structed that the grenade can be easily and readilyremoved therefrom and, furthermore, so'constructed'and arranged that in 'ease'of fire the grenade will be automatically broken and'will dispense the fire extinguishing fluid; :Another object ofthe invention is to provide'a bracket or holder for grenades comprising few parts and a structure that can be economically manufactured.

Another object of the invention is to pro vi'de 'a'fire extinguisher support "or grenade holder so constructed and arranged thatfa plurality "of grenades can be'supported in a manner whereby they will be automatically released and broken in case offire. (Further objects of the invention will appear from the following specification r taken iniconnection with the "drawings,' which form a part of this application, and in which-- Fig. 1" is an-elevational view illustrating one form of the "support constructed in accord ance with'the invention; Y

Theinvention briefly described consists of 'grenade support-ing structure comprising 'a bracket, amember or an arm pivotally associa'tedw'iththebracket and having meansfor supporting and holding a grenade, resilient I means fori swinging the arm relative to the bracket,i;and heat controlled means for hold- 1928. semi ;No. 259,763.

ing the-arm against-{swinging movement. In

certain formsof the invention a pluralityof arms are mounted on the bracket and are adapted to' swing relative' to each other and to the bracket; and heatco'ntrolled means is provided for-holding the arms against swinging.

Further-details of'the invention will appear from' the .foll'owi r g description. V In the form of the invention illustrated in Figs. 1 and 2 there is showira bracket10 having' a stud11 projecting'laterally therefrom. Two arms 121and 1'3'are' mounted on the stud and: are adapted :to swing-relative thereto. ,7 In this particular.embodiment of the invention the arms are formed integral with a pair; of springsl5 and 1 6, each' spring: having one" end 17 fixed to *the stud ll. Each arm has a 100 3 20 211; the-upper end thereof adaptedto -'re st on the upper end portion I of a grenadefl21 and each arm :also has' a loop l 22 adapted to receive the lower endo'f the grenade. I

Each'of the loops-20 has f0rmedtherein an eye 26 adapted to be engage'd by a fusible link27 which holdslthearms against-separation.

In the'embodiment'of the: invention shown in FigsJ-I and 2, the "armsjloops and'springs are all integral and the springs tend to swing the arm 12 in-"one direction, indicatedbythe arrow X, and tendito swing the other arm in the opposite direction, indicated by the arrow Y, the-armsbeing held under tension by the fusible or heat controlled link' 27. g

"An .arm30. extends downwardly from the stud. 11' and is provided" at its lower'end with spikes '31 and 32 adapted to "be engaged by the grenades whenthe'y are released and to break the grenades. Ifdesired the'arm 30 can be dispensed with and'the grenades will be .swunginto contact with. each other, thus pausing them to breakand releasethe fireextinguishing fluid contained .therein.

It will be evident that the grenades can be easilyandreadily removed from thesupports by liftingthe .upper loops 20 so that they can be thrown'atthe fire. ifwa'ny' one is present whenethe'fire breaks out;
